Not sure if anyone else has had this problem or if its the alt but when i let off the throttle at highway speeds i get a whine sound too. It comes from the front passenger side(and yes I do know the alt is there but the sound doesn't, at least to me, sound like its coming from under the hood). I could be mistaken of course.
P.S. anyone had sounds from the manual shifter..like a constant tick (remeniscent of a baseball card in the spoke of a bike).
